The existence of predatory journals is a good reason to use the library databases. The journals, ebooks, and other publications in the databases have editorial oversight. Although some dubious titles may slip in to the collections, for the most part, the publications are reliable sources.
Beware of predatory journals on the Internet that appear to be peer-reviewed reputable journals, but may not be! Predatory journals online appear to be legitimate journals, but they generally charge authors large publication fees even though there is no peer-review process to evaluate the quality of the submissions. The articles they publish may be of low quality or even hoaxes. The publishers of these journals may target scholars with mass emails inviting them to submit an article. Sometimes faculty at universities are listed as being on editorial boards without their knowledge or permission. The titles of the predatory journals can sound very convincing so take a look at the list of predatory journals and predatory publishers on the Open Access website below.
